Confused about making iron oxide?
I am making some iron oxide using the method with the 9 volt and nail in saltwater. Im a little confused however in all the thermite instuctables it says that the wire that bubbles the most is the positve wire. When i connect the (what the battery says) is positive to the nails and insert the negative into the water it seems like more bubbles are kinda comming off the stripped negative wire.
The water is turning a little green(update-its not to green anymore)
There is brown stuff floating at the top of the water.which doesnt burn my skin and smells like metal.
I am using copper wire.
